I'm having trouble saving and restoring STDIN in a script I'm working on. For part of the script I redirect STDIN, so before I do that I save it's location:
local *REAL_STDIN;
open(REAL_STDIN, ">&STDIN");
$this->{'_stdin'} = *REAL_STDIN;

Then later I try to restore the stream using:
if (defined($this->{'_stdin'})){
     local *REAL_STDIN = $this->{'_stdin'};
     if(!(open STDIN, "&REAL_STDIN")){
          return -3;
     }
}

And when I try to run it, I get -3. The same approach works fine with STDERR and STDOUT (though in the restore code they need something like: 
#<snip>
if(!(open STDOUT, ">>&STDOUT")){
#<snip>

Anyone know what I'm doing wrong here?
